The IZT S1000 from IZT is an advanced Digital Signal Generator that operates from 9 kHz to 3 GHz with an instantaneous bandwidth of up to 120 MHz. It has 31 virtual signal generators in one device. This compact multi-channel platform can simultaneously simulate a test environment with multiple sources and can stream multiple signals in parallel with a cumulative bandwidth of up to 320 MS/s. The output signals of all active Virtual Signal Generators are combined and distributed to two independent RF outputs. The IZTS1000 replays recorded or simulated signals with up to 40 MS/s at 12- or 16-bit complex resolution. The user can also generate plain I/Q data using system simulations from Matlab, LabVIEW etc. It is available in a compact 2U form factor chassis that measures 443 x 41.6 x 430 mm with high resolution display and front panel keyboard. The chassis contains all digital processing hardware, synthesizers and RF sections.
